We present results of optical spectroscopic and BVR _ { \mathrm { C } } I _ { \mathrm { C } } photometric observations of 77 pre-main sequence ( PMS ) stars in the Cepheus flare region .
A total of 64 of these are newly confirmed PMS stars , originally selected from various published candidate lists .
We estimate effective temperatures and luminosities for the PMS stars , and comparing the results with pre-main sequence evolutionary models we estimate stellar masses of 0.2–2.4 M _ { \sun } and stellar ages of 0.1–15 Myr .
Among the PMS stars , we identify 15 visual binaries with separations of 2–10 arcsec .
From archival IRAS , 2MASS , and Spitzer data , we construct their spectral energy distributions and classify 5 % of the stars as Class I , 10 % as Flat SED , 60 % as Class II , and 3 % as Class III young stellar objects ( YSOs ) .
We identify 12 CTTS and 2 WTTS as members of NGC 7023 , with mean age of 1.6 Myr .
The 13 PMS stars associated with L 1228 belong to three small aggregates : RNO 129 , L 1228 A , and L 1228 S. The age distribution of the 17 PMS stars associated with L 1251 suggests that star formation has propagated with the expansion of the Cepheus flare shell .
We detect sparse aggregates of \sim 6–7 Myr-old PMS stars around the dark clouds L 1177 and L 1219 , at a distance of \sim 400 pc .
Three T Tauri stars appear to be associated with the Herbig Ae star SV Cep at a distance of 600 pc .
Our results confirm that the molecular complex in the Cepheus flare region contains clouds of various distances and star forming histories .
